Domoticz

Hi all,

I currently have a setup on a pi4, I use the gpio to directly switch a 16ch relais card witch is primarily for central-heating usage. The rest is all zigbee or wifi /mqtt
As the pi is using some SD cards and this gives the most irritating issues, like currently loosing zigbee devices randomly
I willing to upgrade current setup but not sure whats best to do, keep using a Pi 4 or 5 or use a VM on proxmox and replace the gpio with a esp32 on a 16ch card etc.

So what would be a good reliable solid replacement? Budget say €300,- (seems a reasonable budget to me)

A RPi4 with a good SD card and a good power supply (!) should do the trick.....
That zigbee is losing nodes should have nothing to do with SD card but with the zigbee controller stick as there the connection is stored.
A bad power supply can give a lot of issues!
Perhaps moving the gpio to esp will also help.

Get this for your RPi4. Works wonders

I don't agree in total Walter, I had often issues with the regular SD cards, now im usinf the high endurance and I now sins a single year have strange behaviour again.
Yesterday I restarted the device as as dzvent script of 12 line gave a error on line 17 (the previous attempt) and even the runAfter was constant the issue and already replaced, but kept popping up in the log on that script. So a reboot and tried again, all of a sudden 6 zigbee devices where gone, this morning I had to remove them manually out og z4d and in domoticz, after pairing all worked fine till this afternoon, 5 other devices all of a sudden gone! To me that is strange behaviour! SD cards are a cheap fix to replace.

So thats why i have the question whats a good solution for a steady smart home setup. Btw the powersupply is This one It only powers the pi4

@sjonnie this mmc card adpter isnt a bad idea! I didnt think of that as a SD replacment.

You must be joking, right? I sincerely hope you’re not using that 12 volt power supply for the Raspberry Pi, which needs 5 volt only!

By the way, the reply of Waltervl was spot on.

And Sjonnie2017 is referring to an NVME SSD and not to mmc memory.

I wish you all the best with your setup.


(I’m a happy RPi4 user (on 5 V) with Domoticz and the sonoff Zigbee dongle using the Z4D plugin and a good SD card, running rock stable for several years now)

I m on a PI3 with Domoticz and deconz running on it, on the same SD card since 3 years (the new one is still on the box) ^^.
I think Domoticz is the lighter home automation application you can find, I m sure it can run on a Raspberry 0.

But it depend of your devices, for exemple if you use Cameras ....

No camera at all on the pi, its the pi with a 16ch relais card. On the pi runs domoticz and mqtt and thats it.
I replaced the card and now it's solid again. Not sure what goes wrong on the pi.

@WouterO, no not the 12v but the 5v

Oh, I am relieved! The pic on the link you previously included said ‘12 V’, therefore my worry and slight panic.
I am happy that replacing the sd card did the trick!
